Sensata Cynergy3 Paddle Flow Switch Sensor

Many machines stop working because the flow of liquid is not monitored correctly. When flow drops too low, pumps can overheat; when it rises too high, pipes may burst. Both situations cause costly downtime and repair work. The Sensata Cynergy3 Paddle Flow Switch Sensor LFS Series Liquid 15-83 L/min watches the flow continuously and gives an instant on/off signal, so you can protect equipment before damage occurs.

Sensata Cynergy3 Paddle Flow Switch Sensor LFS Series Liquid 15-83 L/min with Sensata

Imagine a tiny paddle that moves with the liquid and tells your controller exactly when flow is out of range. That is what this sensor does. It is built for water, glycol mixes or light oils and fits standard 1 inch NPT or 3/4 inch BSP pipe threads. If you need a reliable way to stop a pump or trigger an alarm when flow is wrong, this Sensata device gives you that safety net.

Usages

You can mount the switch on cooling water loops of CNC machines, on hydraulic oil recirculation lines, in beverage processing tanks, or in farm irrigation systems. It works with temperatures from -30 C to +75 C (up to +150 C for the H version) and handles pressures up to 20 bar. The stainless-steel paddle resists corrosion, so it stays accurate even in harsh environments.
